Stalker, I doubt that the Lapua brass will make your gun more accurate than the others mentioned but it will most likely last a lot longer if you're shooting fairly hot loads. Lapua brass is known for keeping primer pockets tight much longer !! --- RHB ---( PM sent )
Found some old lake city brass. Has anyone had good luck resizing it for 270 win? Any reports on issues with performance?
Half of my 270 brass has an '06 headstamp. When using re-formed mil brass be aware of volume issues(casued by heavier case wall construction) with mil- brass and the fact you may need to remove the crimp. Personally I'd use either factory 270 or "06 brass unless I had a bunch(enough for the life of the rifle) of the lc brass.
